摘要
用户电力消费数据安全是智能电网实施过程中需要解决的问题。针对智能电表中高频数据与低频数据安全性要求不同,文章提出一种基于虚拟环架构的电力用户隐私保护方法。首先使用NTRU加密系统对用户请求数据进行加密,然后建立高频数据与低频数据传输通路。低频数据在环外传输,高频数据在环内实现匿名性,并使用动态交易令牌聚合用户请求。这种隐私保护方法保证了电网操作与账单计算等功能的有效性,实现了用户电力消费数据隐私保护的完整性,提高了通信效率。
The security of user power consumption data is a problem that needs to be solved in the implementation of smart grid. For the security requirements of high-frequency data and low-frequency data are different in the smart meters, this paper proposes a privacy protection method for power users based on virtual ring architecture. First, using the NTRU encryption system to encrypt the user request data, then constructing the transmission paths of high-frequency data and low-frequency data. Low-frequency data is transmitted outside the ring. High-frequency data is anonymized in the ring, and user requests are aggregated with dynamic transaction token (DTT) . The privacy protection method guarantees the validity ofgrid operation and bill calculation, realizes the integrity of privacy protection of user power consumption data ,and improves the communication effciency.
